Victory! I went to the boneyard and grabbed a crusty one off a wrecked '06 Commander (right in front on block), plugged it in and got more or less correct voltages in circuit, ie .26 or something KOEO. Drove it a few miles...no codes. So the OEM stuff off a junker is better than the new aftermarket stuff....again!
Maybe a word of advice: When you buy a new car or truck, maybe the first thing you should do to the motor is unplug every weather-tight sensor one at a time and put some silicone grease in each one so they actually come off when you need them to instead of snapping the plug retention or breaking the F'n lock tabs! Some of these are near impossible to unplug without a pair of pliers.
